Delivery of benefit agents

ABSTRACT

The present invention relates to a cleaning composition comprising an immiscible liquid system having at least one liquid-liquid interface with an interfacial tension greater than 5 mN/m. The less polar solvent in the system has a carbon chain length of at least 4, or is a silicone with more than 3 SiO units. The composition furthermore comprises from 0.001-20% by weight of a benefit agent such as a fluorescer, a dye transfer inhibitor, a fabric softening agent or an anti redeposition agent. The compositions provide for an improved delivery and efficacy of the benefit agents in e.g. a fabric cleaning process.

TECHNICAL FIELD

The invention relates to a cleaning/washing composition and to animprovement in a method or process of cleaning/washing using suchcleaning/washing composition. In particular, the cleaning/washingcomposition is directed to provide for an enhanced delivery of benefitagents by a system of immiscible liquids with high interfacial tension.

BACKGROUND AND PRIOR ART

Conventionally fabric is cleaned using water and a detergent surfactantsystem which is known as wet cleaning. Surfactants adsorb on both fabricand soil and thereby reduce the respective interfacial energies and thisfacilitates the removal of soil from the fabric. Alternatively it isdone by a process called dry cleaning where organic solvents such asperchloroethylene (PCE), petroleum based or Stoddard solvents,chlorofluorocarbon CFC-113 and 1,1,1-trichloroethane are used, all ofwhich are generally aided by a surfactant. The organic solvent helps inthe removal of oily soil in the presence of detergents. Soil removal canbe achieved by a small reduction in interfacial tension. The particulatesoil is largely removed by providing agitation.

It is known that the efficacy of fabric cleaning compositions can beenhanced by adding several benefit agents to the formulations such asfabric softeners, fluorescers, dye transfer inhibitors, opticalbrighteners etc. However, these pose a problem when formulated alongwith a surfactant system. Thus, for example, fabric softeners aretypically cationic and suffer from instability during storage whenassociated with anionic detergent actives in formulations. There willalso be a problem relating to the viscosity of the formulations whenthey are associated with ethoxylated nonionic surfactants and thisproblem will be more pronounced at temperatures higher than 37° C.

U.S. Pat. No. 3,640,881 (Hoechst Celanese Corp.) discloses dry cleaningcompositions containing an hydrophilic optical brightener and detergentmaterial compatible therewith to simultaneously clean and brightentextile structures and particularly white garments having a significantmanmade fiber content. This technology is based in part upon thediscovery that in conventional organic dry cleaning systems awater-dispersible optical brightener in the presence of a small volumeof water can function as a brightness restorer preventing the textilestructures, when being dry cleaned, from dulling, fading, yellowing oracquiring other undesirable characteristics. It is essential to employ adetergent material, especially of the amphoteric type, to enhance thebrightening effect.

Our earlier-filed co-pending application WO-A-01/90474, published onNov. 29, 2001, discloses a process of cleaning fabric using theliquid-liquid interface of at least two immiscible liquid phases with aninterfacial tension greater than 5 mN/m, under agitation. It has beendemonstrated therein that effective cleaning by this immiscible systemcan be achieved in the absence of other detergent actives and benefitagents.

The organic solvents used for cleaning are generally toxic and also poseother problems, as they are inflammable and hence create potential firehazards. Another major concern in solvent cleaning is the tendency ofvapour loss from the cleaning system into the atmosphere especially whenthey are used at elevated temperatures. Solvent cleaning processesgenerally employ chlorinated solvents that are linked to ozonedepletion. Several attempts have been made to avoid these problems andfind suitable substitutes.

Regardless of the type of solvent used, which may be water or organic,agitation of garments in the cleaning medium is essential to acceleratethe removal of the soluble soil or the insoluble, particulate soil.During dry cleaning when a surfactant is used, a maximum of about 10% ofwater is also used along with the solvent system in order to facilitatethe removal of water soluble stains.

Our copending application 999/MUM/2001, filed on Oct. 12, 2001, teachesa method of cleaning fabric using an immiscible liquid phase in whichthe less polar solvent has a carbon chain length greater than 6 and/oris a silicone with more than 3 SiO units to circumvent the problem oftoxicity, flammability, and environmental impact whilst retainingsuperior cleaning of fabric.

SUMMARY OF THE INVENTION

It has now been found that the efficacy of the benefit agents used incleaning/washing systems can be improved without encountering theproblems in use of conventional surfactant systems, by the use of animmiscible liquid system having an interfacial tension greater than 5mN/m, wherein the less polar solvent has a carbon chain length of atleast 4, and or is a silicone with more than 3 SiO units.

Thus according to an aspect of the present invention there is provided acleaning/washing composition comprising:

i. an immiscible liquid system with an interfacial tension greater than5 mN/m, wherein the less polar solvent has a carbon chain length of atleast 4 and/or is a silicone with more than 3 SiO units; and

ii. 0.001-20% of one or more benefit agents (as hereinafter more fullydescribed) that is soluble in at least one of the phases.

Preferably the less polar solvent has a carbon chain length, greaterthan 6. It is particularly preferred that the concentration of the mostpolar liquid is 10.1-90% (v/v) of the immiscible system and the carbonchain length of the less polar solvent is greater than 12 and morepreferably greater than 16.

In accordance with another aspect of the present invention there isprovided an improved method of cleaning/washing of fabrics comprisingcarrying out said step of cleaning/washing under agitation using acleaning/washing composition comprising:

DETAILED DESCRIPTION OF THE INVENTION

Thus according to the essential aspect of the present invention there isprovided a fabric cleaning composition comprising an immiscible liquidsystem having an interfacial tension greater than 5 mN/m and one or moreof said benefit agents. The delivery of the benefit agents is enhancedby the use of the immiscible liquid system. Interfacial tension may bemeasured using various techniques, such as sessile drop, pendant drop,spinning drop, drop volume or Wilhelmy plate method. For the purposes ofthe present invention, interfacial tension is measured by the Wilhelmymethod, using a Kruss Processor Tensiometer K12, at 25° C. For somesystems, the interfacial tension may change whilst undergoing shearingforces typically encountered in a wash process. It is customary to referto the interfacial tension under these conditions as a “dynamicinterfacial tension” (DIFT) and this may be measured by a maximum bubblepressure technique.

Benefit Agents

The benefit agents may be selected from fluorescers, surfactants,hydrotropes, enzymes, bleaches, dye transfer inhibitors, opticalbrighteners, fabric softeners, anti redeposition agents, electrolytes,polymers, builders, perfumes, anti-wrinkling agents, easy-ironing agentsetc. The level of these agents range between 0.001-20% by weight of thecomposition. The level of the fluorescers is preferably in the range0.001-0.5%, dye transfer inhibitors in the range 0.001-1%, fabricsofteners 0.001-20% and anti-redeposition agents 0.001 to 1% by weightof the composition.

Solvents

The solvents that can be used in the immiscible liquid system of theinvention should be such, that the liquid immiscible system has aninterfacial tension of greater than 5 mN/m. The more polar solvents canbe selected from water, aromatic solvents, halogenated solvents such aschloromethane, 1,1-dichloroethane, perchloroethylene,carbontetrachloride, 1,1,2-trichloro-1,2,2-trifluoroethane,chlorobenzene, bromobenzene, heterocyclics etc, and alcohols, ethers,esters, and ketones with less than 4 carbon atoms. Preferably the morepolar solvent is water. Mixtures of solvents can also be used.

The less polar solvents that have a carbon chain length of at least 4,preferably greater than 6 may be selected from branched and linearalkanes (chemical formula CnH2n+2 where n is at least 4), including butnot limited to hexane, heptane, octane, nonane, decane, dodecane,tridecane, tetradecane, pentadecane etc. and mixtures thereof.Commercially available mixtures of this type include Isopar L (C11-C15alkanes-ex-Exxon) and DF2000 (C11-C15 iso-alkanes; CAS# 90622-58-5,ex-Exxon). They may also be selected from branched and linear alkenesincluding but not limited to octenes, nonenes, decenes, undecenes,dodecenes etc, with one or more double bonds, and mixtures thereof.

Ethers including fluoroethers such as methoxy nonafluorobutane HFE7100(i.e. C4F9-OCH3) and ethoxy nonafluorobutane HFE-7200 (i.e. C4F9-OC2H5);esters such as dibutyl phthalate, dioctyl phthalate, C8-C24 saturatedand/or unsaturated fatty acid methyl esters, and terpenes, such aslimonene, or mixtures of the above may be used. Particularly preferredesters are the C10-C18 fatty acid methyl esters such as methyl laurate,methyl myristate, methyl stearate, methyl linoleate and methyllinolenate and mixtures thereof.

The solvents with more than 3 SiO units may be selected frompolydimethyl siloxane oils. Linear and cyclic siloxanes known as Lx andDx where x is greater than three are suitable examples thereof. Specificexamples include

octamethylcyclotetrasiloxane (D4) (ex-Dow Corning),

decamethylcyclopentasiloxane (D5),

dodecamethylcyclohexasiloxane (D6), decamethyltetrasiloxane (L4) anddodecamethyl pentasiloxane (L5).

Agitation

Regardless of the type of solvent used, which may be water or organic,agitation of garments in the cleaning medium is essential to acceleratethe removal of the soluble soil or the insoluble, particulate soil.Agitation can be provided by impellers that cover the vertical flowprofile or radial flow profile or a combination of both so that thoroughmixing of the immiscible liquids take place. Agitation can be providedby impellers that are of the types known as open curved turbine, turbinetype propeller, axial flow turbine, flat blade turbine, inverted vaneturbine, marine propeller etc. This action may also be accompanied by atumbling action. Optionally agitation can also be provided by acombination of rotation and tumbling action. Other forms of agitationusing gas jets or ultra sound may also be employed. Other forms ofagitation generally known in the art can also be employed provided itensures a good mixing of the immiscible liquid phases.

The nature of the invention, its objects and advantages will be moreapparent from the ensuing description, made with relation tonon-limiting examples of the above identified aspects of the invention.

EXAMPLES 1-10 EXAMPLE 1

Artificially soiled test fabric was prepared using the methodologydescribed below and the effect of the immiscible liquids as the washsystem for the delivery of benefit agents as compared with conventionalaqueous detergent systems.

Preparation of the Test Fabric

Carbon soot N220, Carbot, (15 mg) was added to a 5 mg solution of sodiumdodecyl sulphate in 100 ml of de-ionised water and the mixture dispersedevenly by sonication in an ultra-sound bath for a minimum of 1.5 hours.Swatches of plain white cotton 10 cm×10 cm (Poplin weave, ex HindustanSpinning & Weaving Mills, Mumbai) were dipped into this mixture by handuntil the cotton was observed visibly to be wetted completely (10-20sec). The swatches were then withdrawn from the suspension, and allowedto drain naturally and air-dry overnight.

Determination of Detergency

The initial reflectance at 460 nm, with contribution due to UV excluded,(hereafter referred to as R460*) of swatches of this particulate soiledfabric, prepared as outlined above, was obtained using a MacbethColour-Eye 7000A reflectometer. For detecting fluorescer contribution,the reflectance values at 460 nm, with contribution due to UV included,(hereinafter referred to as R 460) were also obtained. Three of theseswatches were placed into a 500 ml conical flask to which a testsolution of 300 ml of water+0.75 grams of a detergent formulationdescribed in Table 1, was added. The conical flask was agitated at 120rpm for 30 mins at ambient temperature using a reciprocating agitator,which facilitates efficient mixing of the liquids. Following washing theindividual swatches were air-dried and the final reflectance values forthe swatches at R460* determined. The change in reflectance ΔR isdetermined by subtracting the initial reflectance from the finalreflectance; the average change in reflectance for the three separateswatches is presented in the series of Tables set out below.

The data presented in Table 1a show that the brightness of the fabric isimproved significantly when the fluorescer is delivered through animmiscible system such as Soya Methyl ester:water 20:80 than when it isthrough a detergent formulation or pure water system.

EXAMPLES 11-18

ii. Effect on Dye Transfer Inhibition

Three 8×8 cm swatches of commercial black (vegetable dye ex Kanmanitextiles Selam-Tamilnadu) cotton fabric, were placed in a 500 ml conicalflask to which 300 ml of water+0.75 g of the detergent compositiondescribed in Table 2 had been added (Example 11). The initial brightness(Lba Value) was determined using a Macbeth Colour-Eye reflectometer. Theconical flask was then agitated at 120 rpm for 30 minutes at ambienttemperature using a reciprocating agitator, which facilitates efficientmixing of the liquids. Following washing the individual swatches wereair-dried and the final brightness, E (Lba) values for washed swatchesdetermined. The change in brightness is calculated by subtracting thefinal brightness from the initial brightness and the average for thethree separate swatches is presented in Table 2a.

Similarly, the procedure was repeated for other wash systems such aswater+0.75 detergent wash medium and 0.03 g dye transfer polymerChromabond 100 (amphoteric polyvinyl-pyridine betaine-ex ISP, Mumbai)(Example 12), water+detergent wash medium replaced with 300 ml ofdeionised water (Example 13) and water+detergent wash medium replacedwith 300 ml deionised water and 0.03 g dye transfer polymer Chromabond(Example 14), water+detergent wash medium replaced with 300 ml of amixture of HFE7100 (methoxynonafluorobutane ex 3M) and water in theratio 20:80 (Example 15), water+detergent wash medium replaced with 300ml of a mixture of HFE7100 and water in the ratio 20:80 and dye transferpolymer Chromobond (0.1 g/l) (Example 16), water+detergent wash mediumreplaced with 300 ml of Methyl ester CE 1218 (a mixture of methyllaurate, methyl myristate and methyl stearate, ex P&G, Malaysia,CAS#68937-84-8) and water in the ratio 20:80 (Example 17),water+detergent wash medium replaced with 300 ml of Methyl ester CE1218and water in the ratio 20:80 and dye transfer polymer Chromabond (0.1g/l)(Example 18). The average inhibition of dye transfer values forthese systems is reported in Table 2a.

The data presented in Table 2a show that the dye transfer issignificantly inhibited when the washing is performed using theimmiscible system compared to the system containing adetergent/Chromabond. Thus in an oil/water cleaning system this polymerconfers stability on dyes such as vegetable dyes.

The average change in reflectance valuesfor these systems is reported in Table 3a.

The data presented in Table 3a show that the redeposition of soil isinhibited significantly when the washing is performed using theimmiscible system of oil:water (20:80), together with SCMC as comparedto the system containing a detergent/SCMC or even water/SCMC alone. Thisdemonstrates that the benefit of using an SCMC is more efficacious inthe immiscible system than in the detergent system.
